Versuchsvorschrift
A glass Parr bottle was charged with 10% palladium on carbon (0.1 g) wetted with ethanol (10 mL) and a slurry of (2E)-3-[4-amino-2-ethyl-1-(tetrahydro-2H-pyran-4-ylmethyl)-1H-imidazo[4,5-c]quinolin-7-yl]-N,N-dimethylprop-2-enamide (0.32 g, 0.78 mmol) in methanol (200 mL). The vessel was placed on Parr apparatus, evacuated and charged with hydrogen (55 psi). The mixture was shaken at ambient temperature for 48 hours. The reaction mixture was filtered through a 0.2 micron PTFE membrane filter and the filter was rinsed with methanol (100 mL). The filtrate was concentrated to dryness under reduced pressure. The resulting solid was recrystallized from acetonitrile to provide 220 mg of 3-[4-amino-2-ethyl-1-(tetrahydro-2H-pyran-4-ylmethyl)-1H-imidazo[4,5-c]quinolin-7-yl]-N,N-dimethylpropanamide as a white crystalline solid, mp 219-220° C.
